Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently rotating images for display on both internal and external monitors, particularly when capturing vertical images, as they require manual adjustments and complex settings to maintain readability and orientation.
Innovation Solution
An electronic device with a control unit that rotates images on a display unit based on detected rotational angles, synchronizing the orientation of internal and external displays to ensure proper image display without the need for frequent user intervention or additional hardware support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustments and complex settings are used to rotate images for display, then image orientation can be maintained, but user operation becomes complicated and time-consuming
Solution Approach 1:
The system automatically detects the rotational angle of the display unit and performs image rotation without user intervention. The control unit monitors display orientation changes and rotates the image accordingly, allowing the system to serve itself rather than requiring manual user adjustments.
Solution Approach 2:
The system implements a feedback mechanism where the control unit continuously monitors the rotational angle of the display unit and adjusts the image orientation based on this feedback. This closed-loop control ensures the image remains properly oriented regardless of display rotation, eliminating the need for manual settings.
2Adaptability or versatility
If separate rotation controls are implemented for internal and external displays, then each display can be optimized independently, but device complexity increases
Solution Approach 1:
The control unit implements a universal rotation control mechanism that automatically adapts to both internal and external displays. By using a single control system that detects display rotation and applies appropriate image rotation, the patent achieves multi-display adaptability without increasing device complexity.
Solution Approach 2:
The patent combines the rotation control functionality into a unified system that manages both internal and external displays through a single control unit. This merging of control functions eliminates the need for separate rotation controls, reducing device complexity while maintaining adaptability across different display types.
